I just lost like one hundred lines of text including a data sheet I was preparing to start a new topic in development & technical subforum because of the naive way the draft feature is implemented with.
The only thing that is naive here is you relying on the forum to be a permanent archive of your various writings.
14.3 is nothing, I do a lot of edits and 7 days is nonsense.
For a serious writer it is completely possible to suspend writing a post for a while for may reasons, doing more research, finding some lost reference material, carrying out some calculations, re-thinking some points, ... it is more important use-case compared to simple redo. A compromise would be keeping a maximum of 3 last versions and removing the 7 days window for new posts/topics that are not committed yet.
If you're serious about writing anything then you shouldn't be relying on the forum to save all your work for you, especially not ones 'in progress' and being constantly revised. Use a word processor like everyone else then preview it here to see how it looks. You should always have back ups of anything digital that is important and this is nobody else's fault other than your own.
